Influence of stored heat on the choice properties of fine - grained steel welding.
 Urban, Vratislav ; Kubíček, Jaroslav (referee) ; Daněk, Ladislav (advisor)
The diploma thesis is focused on characterization of fine – grained steels, choosing of welding technology and effects of heat transmission on weld joint quality. The effect of transmitted heat on microscopic structure and stiffness of weld have been studied. Based on obtained results the optimal parameters for welding of fine - grained steel have been determined.

CMT advanced application in industrial practice
 Šoulák, Petr ; Sigmund, Marian (referee) ; Kubíček, Jaroslav (advisor)
In presented diploma thesis is studied problematics of welding of high strength steels. This work also describes arc welding in protective atmosphere CMT Advanced. In experimental part of this work is CMT Advanced method compared with conventional arc welding in protective atmosphere in shortcut mode used for welding of Hardox 450 and Weldox 700 E. Comparing of mechanical properties of weld material are realized via transverse tensile testing and measuring of microhardness. Macrostructure and microstructure of weld was evaluated too. In the last part of this thesis is a brief economical assessment of both studied methods.
